So, my bf is really good friends with a girl he has known for about a year now, She knows about me and she even added me on social media and chats to me when they’re on the phone. Anyway recently he’s been saying ‘love ya’ ‘bye mate’ when ending a phone call with her (in front of me) and it’s making me wonder if there’s more to it? He was single when they first met and he said there was nothing in it other than mates when we first got together but he also said if any woman told him he had to stop speaking to her he would tell his ‘gf’ where the door is cos he loves her to bits and wouldn’t stop the ‘friendship’ (I wouldn’t expect that anyway) she’s kinda seeing someone too but I just can’t help thinking there’s something more to it.. something just doesn’t feel right. He asked me if I was jealous over it or going to start getting jealous over it because I did say go and see ****** making a joke about her to see his reaction. Thoughts please?
